The results of Dang et al.'s recent systematic review and meta-analysis suggested that individuals diagnosed with other specified feeding or eating disorder (OSFED) and those diagnosed with specified eating disorders (EDs, such as bulimia nervosa) endorse similar, elevated levels of ED-related cognitions (but not behaviors). The DSM has traditionally conceptualized EDs primarily as disturbances in eating behavior, and the diagnostic boundaries for EDs are based on objective markers, such as behavioral frequencies and weight. Although focusing on objective markers for ED diagnoses and severity indices has advantages (e.g., clinical communication, measurement), pitfalls include diagnostic migration and low emphasis on ED cognitions. Dang et al.'s findings provide a basis for rethinking DSM's conceptualization of EDs as primarily behavioral. This commentary discusses the potential merits and challenges of emphasizing subjective cognitions when assigning ED diagnoses. We explore how objective markers (e.g., behavioral frequency, weight) and subjective experience (e.g., fear of weight gain) may be balanced to improve the clinical utility of ED diagnoses. In all, research that more deeply phenotypes the subjective experiences of people with EDs across contexts, identities, and cultures will enrich our understanding of eating pathology and may inform diagnostic revisions.
最近,Dang 等人的系统评价和荟萃分析结果表明,被诊断为其他特定进食或饮食障碍(OSFED)和被诊断为特定饮食障碍(如神经性贪食症)的个体,其与饮食障碍相关的认知(而非行为)水平相似,且升高。DSM 传统上主要将饮食障碍概念化为进食行为障碍,而饮食障碍的诊断界限则基于客观指标,如行为频率和体重。尽管关注饮食障碍诊断和严重程度指数的客观指标具有优势(例如,临床交流、测量),但也存在一些缺陷,包括诊断转移和对饮食障碍认知的重视不足。Dang 等人的研究结果为重新思考 DSM 将饮食障碍主要概念化为行为障碍提供了依据。本评论讨论了在进行饮食障碍诊断时强调主观认知的潜在优点和挑战。我们探讨了如何平衡客观指标(例如行为频率、体重)和主观体验(例如对体重增加的恐惧),以提高饮食障碍诊断的临床实用性。总之,对不同背景、身份和文化中的饮食障碍患者的主观体验进行更深入的表型研究,将丰富我们对进食病理的理解,并可能为诊断修订提供信息。
